Is there somewhere in the body that can store fluid, apart from the bladder? Most nights I wake to empty my bladder after exactly 4 hours鈥� sleep, but on occasional nights where I haven鈥檛 been to the loo all day previously I have to get up three or four times instead of only once. It鈥檚 obvious that the urine has been building up during the day, but it wasn鈥檛 there in my bladder before I went to bed. So where was it?
